At about 8 o'clock in the morning, Zhen Shifeng, accompanied by two police officers in charge of care, hurried to the police station. www.biquge.info After receiving Bai Feng's call, he was a little uneasy, and the other party did not tell what happened, but it was not difficult to judge from his tone that the matter must be extraordinary.

However, entering the office hall on the first floor of the police station, the police officers were still nervously and busy receiving visitors as usual, or crouching on the desk and carefully flipping through the documents in their hands, and the work was carried out in an orderly manner. Sure enough, after ascending the escalator on the second floor, several blinking police lines were the first to come into view, in stark contrast to the downstairs, the police officers here all looked panicked and solemn, everyone was whispering, not knowing what they were talking about.

Also with a solemn face was Bai Feng, seeing Zhen Shifeng coming, he just spat coldly: "Don't make a sound, follow me!" ”

"Isn't it............ Zhao Yunfei had an accident. ”

Bai Feng stopped abruptly, looked back at Brother Feng, and could see from his eyes that his mood was quite complicated, and then sighed, and said: "The one who was killed around two o'clock in the morning was in his own office, this is the second person among the five people of our detectives, God knows who will be next." ”

Zhen Shifeng suddenly chuckled in his heart, and his ominous premonition became a reality. He didn't say much, but quietly followed behind, and an inexplicable sense of fear began to rise in his heart, not because he was afraid of death, but because he was afraid of the process of waiting for death, and that kind of waiting was an inner torment, and the only thing they could do was to end it as soon as possible, but the difficulty could be imagined.

"Uncle Bai, Brother Feng!" Wei Liqiu waited outside the door of the crime scene early, and greeted him from afar. In fact, he was the first witness to the murder, and he originally hoped to come a little earlier to talk to Zhao Yunfei about the case the night before, but what turned out to be a tragic scene in front of him.

In addition to several police officers, Wei Liqiu was accompanied by the deputy director of the police station, a middle-aged woman about 40 years old. This person Zhen Shifeng knows, and he is also one of the few 'competent' policemen he identifies, and he has a good personal relationship with him. By the way, the landlord of the residence where Brother Feng lives is also the husband of the deputy director's family.

"It's really great that both of you can come here, to be honest, I can't help anything in this situation at the moment, I'm afraid that Director Zhao's death will lead to a series of consequences, which is unimaginable." The deputy director's eyebrows were tightly locked, looking quite worried.

"Well, what about the corpses, we want to go in and have a look." Bai Feng said first, it was very necessary for him to get first-hand information.

"The technical department has already surveyed the scene, but the body has not been removed yet, so please feel free to do so before the autopsy by the forensic team. Oh, by the way, Liqiu, didn't you just say that you found a few suspicious points, and it just so happens that everyone is there, so why don't you talk about your opinion? ”

"It can't be said to be suspicious, it can only be said to be some speculation, and it's very strange............ Well, it's okay, let's wait for Uncle Bai and Brother Feng to finish surveying the scene. ”

Zhen Shifeng noticed the expression on Wei Liqiu's face, which was an expression of doubt, uneasiness, and excitement. Doubts express his slightly different views on the case, uneasiness is a trace of worry about serial homicides, and as for excitement, it is the normal feelings that a detective exudes when facing difficult cases and difficult enemies, and the enthusiasm for solving the case, enjoying the whole process of solving the case, this special expression is by no means understandable to ordinary people.

"Well, nice expression, but because of this, I can't be discouraged, I can't fall behind, and I can't admit defeat, because there is always only one word in my dictionary, and that is, win!"

………………………………

The corridor on the second floor of the police station is arranged in the shape of an 'mouth', with rooms with different functions on both sides of the corridor, while the director's office is located at the north-east corner, which is located at the junction of the east and north corridors.

The director's office is small and the facilities are quite simple. On one side of the door is a row of cabinets for important data files, which have not been tampered with so far. At the back was an ordinary desk with stacks of papers, soaked in blood. Zhao Yunfei's body was lying on the table like that, the left side of his neck was pierced and cut in a straight line, and blood was splashed all over the table, his method was no different from Cai Jun's case, in addition, there was also the red β mark left on the wall was quite eye-catching, and it was not difficult to determine that the two cases were likely to be committed by the same person, or related to someone.

"A form of murder like this must require a sudden attack from behind, a stab in the neck of the deceased. But the chair Zhao Yunfei was sitting on was only one meter away from the back wall, and there was no covering, if he openly stabbed behind the back, Zhao Yunfei couldn't have noticed it, unless he ............" Bai Feng paused, his eyes couldn't help but fall on the stack of files that Zhao Yunfei had flipped through before his death, which was a file about the β case two years ago, there were as many as twelve volumes.

"Unless there are four possibilities!" Zhen Shifeng suddenly continued: "First, Director Zhao had fallen into a coma before the murderer's assassination, so it was naturally difficult to detect the murderer's actions. Second, the murderer and the deceased were acquaintances, and in the course of the conversation between the two, the murderer went around the back of the deceased and suddenly attacked. In the third case, the murderer suddenly sneaked in from the window on the back wall and gave the unsuspecting Zhao Yunfei a knife. ”

"But none of these three are likely, because ............"

"Because it's a secret room, right?"

Wei Liqiu nodded, he who had already cooperated with the first round of investigation naturally knew this, so he said: "That's right, the windows and doors are locked, I found something strange when I came to visit in the morning, according to the words of the police officer on duty, Uncle Zhao has the habit of locking himself in the house when he is in the office, and Uncle Zhao's death time is roughly two o'clock in the morning, and no one has entered or left the director's office between one and seven o'clock in the morning, so the three possibilities just now are very small." Of course, special circumstances are not ruled out, such as the police officer on duty falling asleep and failing to detect someone sneaking in, etc. ”

"Hey, little brother, you can't say that!" The two officers on duty looked a little embarrassed.

"It's just my reasoning, anything is possible, and of course, I'm sure you won't lie." Wei Liqiu quipped: "There is another interesting thing, Aunt Deputy Director, the murder weapon is still there, right?" ”

"The murder weapon?" Bai Feng and Zhen Shifeng were startled at the same time.

Under the orders of the deputy director, the murder weapon was soon presented. As the two expected, the murder weapon was exactly the same as the dagger left in Cai Jun's case.

"Because I showed up late last night, I didn't see the murder weapon. And today, after my observation, I found that this dagger is not ordinary! Wei Liqiu picked up the murder weapon, weighed it, and measured the size, "If you are not a lover who knows the military very well, I am afraid you don't know the true face of this dagger." ”

Speaking of the military, this is Zhen Shifeng's hard injury, and it is normal to miss the clues on the murder weapon.

"M286 special-purpose saber, a small saber for the military and special agents of the United States, 12 centimeters long and 3 centimeters wide, made of special alloys, light weight, small size, easy to carry, so it is mostly used for close-range assault combat or assassination. M286 is forbidden to be sold in the United States, and it is impossible to see it in the Celestial Empire, but now there are two in one go, and I have to say that the murderer is very likely to have a background in the United States. ”
